"...and I already did uncheck the box that says "Create new clip on Start/Stop".. but its still happening."

Oh, and Michael...
If your capture settings are not listening to you, take your FCP User Data folder out of the user/library/preferences folder and drag it to your desktop. Then try things out. If that fixes this, then your prefs got corrupted. If it doesn't help, drag the folder back and replace the new one and try something else. I do this once in a while when weird things happen.

YESYESTHANKYOUTHANKYOU!!! IT worked.. I got clean audio + no dropped frames when importing using hdv-108024p! I was right.. you do RULE!

I captured footage recorded with th XH A1 at 1080/50i and then also at 25F and found the way to edit in FCP 5.0.4 using HDV 1080/50i both shots.
This happened on a G5 PowerPC, without rendering.
I captured the same footage on a MacBookPro Intel, using FCP 5.1.2 and found the option to use HDV 25p preset, as I was reading here in these notes, and worked great.
When I brought that final movies in the PowerPC they did not recognized from FCP 5.0.4 but also from no other application and was impossible to see them.
I tried to copy the codec that I saw on FCP 5.1.2, missing on FCP 5.0.4 and that were inside the Custom Settings -> "HDV - 1080i50 FireWire Basic.fcpre" and "HDV - 1080i60 FireWire Basic.fcpre" plus more about XDCAM HD etc, but they did not give the possibility to let the movies play...

I can't find the HDV - 1080p24 setting. All I see is the HDV, and HDV-Apple Intermediate Codec. The DVCPRO HD codecs have the advanced pulldown feature for 24f, but they don't capture correctly with the Canon HX AI.
